MetadataStore
Author: Axicon Labs Limited
Base contract that can store two-deep objects with large value sizes at deployment time.
State Variables
metadata
Stores metadata pointers for future retrieval.
Can hold 2-deep object structures.
Examples include {"A": ["B", "C"]} and {"A": {"B": "C"}}.
The first and second keys can be up-to-32-char strings (or array indices.
Values are pointers to a certain section of contract code: [address, start, length].
The maximum size of a value is theoretically unlimited, but depends on the effective contract size limit for a given chain.
mapping(bytes32 property => mapping(uint256 index => Pointer pointer)) internal metadata;
Functions
constructor
Stores provided metadata pointers for future retrieval.
constructor(bytes32[] memory properties, uint256[][] memory indices, Pointer[][] memory pointers);
Parameters
| Name | Type | Description |
|---|---|---|
properties | bytes32[] | An array of identifiers for different categories of metadata |
indices | uint256[][] | A nested array of keys for K-V metadata pairs for each property in properties |
pointers | Pointer[][] | Contains pointers to the metadata values stored in contract data slices for each index in indices |
